Crescent Lufkin CLA100B 100-Foot Professional Aluminum Chalk Reel Set

The Crescent Lufkin CLA100B 100-Foot Professional Aluminum Chalk Reel Set is an industrial snapping layout tool engineered for marking straight reference gridlines across framing studs, plywood subflooring, drywall assemblies, and concrete foundation forms. Built with a high-impact die-cast aluminum housing, this marking tool features a 6:1 planetary gear ratio that retracts the 100-foot reinforced braided line six times faster than standard 1:1 drive reels. Outfitted with a one-hand hub lock mechanism to anchor line tension, a mess-free one-way refill valve with a quarter-turn release cap, a recess-nesting end hook that eliminates tool pouch snagging, and an included 3-ounce bottle of high-visibility blue layout chalk, this compact tool executes one-person alignment tasks.

Best Used For:

  • Solo Framing & Subfloor Layout: Snapping continuous 100-foot alignment gridlines across plywood decking and floor joists using the one-hand hub lock.
  • Roofing Shingle & Sheathing Grid Alignment: Marking straight chalk reference lines across sloped plywood roof decking prior to shingle installation.
  • Concrete Formwork & Wall Footing Layout: Establishing bright blue reference guidelines on poured concrete foundations and masonry block courses.

Key Performance & Safety Features

  • 6:1 Planetary Gear Drive System: High-speed internal gearing rewinds the entire 100-foot braided line rapidly to reduce downtime between snaps.
  • One-Hand Hub Lock Mechanism: Integrated spool brake locks the cord at exact distances to allow single-operator tensioning and line snapping.
  • Recessed Nesting End Hook Storage: Steel end hook folds flush into the aluminum case housing to prevent snagging inside pockets and tool bags.
  • One-Way Refill Valve & Quarter-Turn Cap: Sealed inlet valve allows mess-free chalk filling while the quarter-turn top provides full interior access.
  • Reinforced High-Retention Braided Cord: Specialized line weave maximizes chalk powder retention while minimizing line overspray and ghosting.
  • Die-Cast Aluminum Jobsite Housing: Lightweight metallic body withstands high-altitude drops onto concrete slabs and rough jobsite surfaces.

What's Included

  • (1) Crescent Lufkin CLA100B 100-Foot Professional Aluminum Chalk Reel
